Lenovo V330-14 Replacement Battery 7.72V 5B10P98182

Lenovo V330-14 Series — 7.72V Li-ion Replacement Battery (L17M2PB5)

This is a 7.72V, 4800mAh (37.06Wh) Li-ion cell for the Lenovo V330-14 notebook. It fits the V330-14IKB and related IKB variants listed under OEM part numbers L17C2PB5, L17L2PB5, L17M2PB5, 5B10P98182, and several adjacent SKUs. Swap it in when the original cell no longer holds a usable charge or the laptop has lost portability entirely.

• V330-14IKB platform fit: All V330-14IKB variants share the same two-cell 7.72V architecture and a single connector pinout. The BMS handshake across these SKUs is identical, so one replacement cell covers the full IKB sub-family without adapter or modification.
• Bench tested on actual hardware: We cycled this cell through charge and full-load discharge on a V330-14IKB unit. The BMS accepted the cell on first insertion, reported state-of-charge correctly, and held the charge limit without tripping an overcurrent fault under sustained CPU and display load.
• Post-install discharge cycle on the V330-14: After fitting, run a single full discharge until the laptop hibernates on its own, then charge uninterrupted to 100%. The V330-14 BIOS uses this cycle to reset its battery learn table — skip it and the fuel gauge will read inaccurately for weeks.

BIOS reporting poor battery health immediately after fitting a new cell

The V330-14 BIOS stores charge history and health metrics in EEPROM tied to the original cell. When a new cell arrives, those values no longer match the actual chemistry, so the BIOS flags health as poor or unknown — even though the cell is brand new. This is not a fault with the replacement. Running one complete discharge-to-hibernate followed by a full uninterrupted charge lets the BIOS rewrite its learn table against the new cell's actual voltage curve. After that single cycle, the health warning clears and the fuel gauge tracks correctly.

Laptop shuts down abruptly at 20–30% charge shown on the V330-14

This happens when the cell can no longer sustain voltage under the combined draw of full CPU load and the display backlight — the voltage drops below the BMS cutoff threshold faster than the fuel gauge can track it. The gauge shows 20–30% remaining because it is reading a rested-cell estimate, not a live load-adjusted voltage. On an aged original cell this is a sign of cell failure; on a replacement cell it usually means the BIOS learn cycle has not been completed yet. Run one full discharge to hibernate-cutoff, then charge to 100%, and check whether the shutdown point moves — if it does not, verify the resting open-circuit voltage sits at or above 7.6V after a full charge.
